Use Bath Scrubby To Wash Car

When cleaning your car and the bug spots are hard to get off, just use a nylon bath scrubby ball that comes with many bath sets. They are soft and will not scratch the paint, but will work wonderfully on those greasy bug spots and black tar.

You can spray the tar, grease, and bug spots with WD-40. It will soften/dissolve the debris and you can wash it off without harming the clear coat. You should only 'scrub' your car's clear coat finish with a cotton terry cloth or microfiber cloth. That is, if you want to avoid 'spider webs' in your shine.
